Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with various embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0039] Such as figure 1 As shown, in an embodiment of the present invention, the method for eliminating errors between different high-speed serial links through FIFO includes the following steps:

[0040] S1. Receive the synchronous data on each link, and store the synchronous data in the FIFO correspondingly set in each link; as figure 2 As shown, in the data transmission process of the high-speed link, a series of original data frames 100 need to be divided into several synchronous data 110 for parallel transmission on each link, so as to increase the transmission rate. The links include several, a...

Abstract

The invention provides a method for eliminating error between different high-speed serial links through FIFO (First Input First Output). The method comprises the following steps of: S1, receiving synchronous data on each link and storing the synchronous data in FIFO which is correspondingly arranged in each link; S2, setting a Pop time point and simultaneously extracting the synchronous data from the corresponding FIFO on each link at the Pop time point; and S3, recovering the synchronous data which is extracted from the corresponding FIFO from each link into an original data frame. Compared with the prior art, the synchronous data transmitted on each link is stored in each FIFO which is correspondingly arranged, and data in each FIFO is simultaneously extracted out when the FIFO is read, so that Skew between every two links is eliminated, and furthermore, the data which is transmitted by the high-speed serial link is more easily recovered.

Description

technical field [0001] The invention relates to the technology in the field of network communication, in particular to a method and system for eliminating errors between different high-speed serial links through FIFO. Background technique [0002] At present, in many high-speed data transmission applications, in order to ensure the rate of data transmission, it is often necessary to divide a group of data frames into several synchronous data, and then transmit the synchronous data in parallel on several high-speed serial links, and finally Restore each synchronization data to an original group of data frames at the receiver. [0003] However, due to actual physical transmission reasons, such as different data transmission rates of each link, there will be an error time between the synchronization data between each link, so that the reception on each link is not received at the same time. To each synchronized data, which brings difficulties to data recovery. Contents of th...
